Insprion 13 7353's H and L Keys don't work when touch screen is connected.
As the subject suggests, the touch screen works fine when it's connected... however, when it's connected, the H key and the L key don't work. To fix this, I have to disconnect the digitizer ribbon cable from the logic board (disabling the touch screen), then all the keys work as they should. If I reconnect the touch screen, the H and L keys stop working.
It's not the screen, that's been replaced twice trying to solve this continuing issue. Any ideas?
